With the victims that Turkey gave in yet another terrorist attack over the past year it pays for its struggle against the so-called Islamic State, Middle East analysts told the Bulgarian National Radio. The reason for the Tuesday attack is that over the last six months the Turkish artillery has been shelling jihadists across the Syrian border. Turkish authorities have implemented stricter border controls in a bid to annihilate the jihadist organization in its territory, argued Thomas Pierret, professor in Modern Islam at Edinburgh University. He sees the airport blast as an attack on Turkey’s tourism sector and its economy. Turkey contributes a lot to the offensive against the extremists in Syria, said Gallia Lindenstrauss from the Institute for National Security Studies in Tel Aviv. She said she expected that after the painful blow Turkey would build up its actions against Islamic State. The conflicting interests of international players continue to be the main reason for the lack of joint efforts against ISIS. According to Thomas Pierret reconciliation between Erdogan and Putin will hardly erase the differences between them in Syria.
